Tips for driving with Active Distance
Assist DISTRONIC General notes
Pay particular attention in the following traffic
situations:
R Cornering, entering and exiting a bend: the
ability of Active Distance Assist DISTRONIC to detect vehicles on bends is limited. Your vehi-cle may brake unexpectedly or late.
R Vehicles driving in a staggered formation:
Active Distance Assist DISTRONIC may not
detect vehicles that are not driving in the mid- dle of their lanes. The distance to the vehiclein front will be too short.
R Other vehicles changing lane: Active Distance
Assist DISTRONIC has not detected the vehi-
cle cutting in yet. The distance to this vehicle
will be too short.
R Narrow vehicles: Active Distance Assist
DISTRONIC has not yet detected the vehicle
in front on the edge of the road because of its
narrow width. The distance to the vehicle in
front will be too short.
R Obstacles and stationary vehicles: Active Dis-
tance Assist DISTRONIC does not brake for obstacles or stationary vehicles. If, for exam-
ple, the detected vehicle turns a corner and
an obstacle or stationary vehicle is revealed,
Active Distance Assist DISTRONIC will not
brake for them.
R Crossing vehicles: Active Distance Assist
DISTRONIC may mistakenly detect vehicles
that are crossing your lane. Activating Active
Distance Assist DISTRONIC at, for example, a
traffic light with crossing traffic could cause
your vehicle to pull away at the wrong time.
In such situations, brake if necessary. Active
Distance Assist DISTRONIC will then be deacti-
vated.
Active Distance Assist DISTRONIC with
Active Steering Assist General notes
Active Distance Assist DISTRONIC with Active
Steering Assist aids you in keeping the vehicle in
the center of the driving lane by means of mod-
erate steering interventions in a speed range
from 0 - 125 mph (0 - 200 km/h).
It monitors the area in front of your vehicle by
means of camera system 0043at the top of the
windshield.
In a speed range from 0 - 37 mph (0 - 60 km/h),
the advanced automatic pulling away function
focuses on the vehicle in front, taking into
account lane markings, e.g. when following vehi-
cles in a traffic jam.
At speeds of more than 37 mph (60 km/h),
Active Steering Assist focuses on clear lane
markings (left and right), focusing on the vehicle
in front only if clear lane markings are not pres-
ent.
If these conditions are not present, Active Steer-
ing Assist cannot provide assistance. Driving systems

General notes Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. A parking symbol indicates a suitable parking space. Active steering inter-
vention and brake application can assist you
during parking. Parking Assist PARKTRONIC is
also available (Y page 188).
Important safety notes Active Parking Assist is merely an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. Make sure that no persons, ani-
mals or objects are in the path of your vehicle.
When Parking Assist PARKTRONIC is deactiva-
ted, Active Parking Assist is also unavailable. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users or
objects. There is a risk of an accident.
Pay attention to other road users or objects.
Stop the vehicle if necessary or cancel the
Active Parking Assist parking procedure.
! If they cannot be avoided, drive over obsta-
cles such as curbs slowly and at an obtuse
angle. Otherwise, you may damage the
wheels or tires.
Active Parking Assist may also show parking
spaces that are not suitable for parking, e.g.: R where parking or stopping is prohibited
R in front of driveways or entrances and exits

General notes Rear view camera
0043is an optical parking and
maneuvering aid. It shows the area behind your
vehicle with guide lines in the multimedia sys-
tem.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
i The text shown in the multimedia system
display depends on the language setting. The following are examples of rear view camera
displays in the multimedia system.
Important safety notes The rear view camera is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering and parking. Make sure
that there are no persons, animals or objects in
the maneuvering area while maneuvering and
parking in parking spaces.
Under the following circumstances, the rear
view camera will not function, or will function in a limited manner:
R if the trunk lid is open
R if there is heavy rain, snow or fog
R at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in win- ter Driving systems

R
you accelerate hard, e.g. kickdown.
R you brake hard.
R you steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
R you cut the corner on a sharp bend.
To ensure that you are warned only when nec-
essary and in good time if you cross the lane
markings, the system detects certain conditions
and warns you accordingly.
The warning vibration occurs earlier if:
R you approach the outer lane marking on a
bend
R the road has very wide lanes, e.g. a freeway
R the system detects solid lane markings
The warning vibration occurs later if:
R the road has narrow lanes
R you cut the corner on a bend Driving Assistance Plus package
General notes The Driving Assistance Plus Package consists of
Active Distance Assist DISTRONI C(Ypage 171),
Active Blind Spot Assist (Y page 209) and
Active Lane Keeping Assist (Y page 211).
Active Blind Spot Assist General notes
Active Blind Spot Assist monitors the areas on
either side of the vehicle that are not directly
visible to the driver with two lateral, rear-facing radar sensors. A warning lamp lights up in the
exterior mirrors and draws your attention to
vehicles detected in the monitored area. If you
then switch on the corresponding turn signal to
change lanes, you will also receive a visual and
audible collision warning. If a risk of lateral col-
lision is detected, corrective braking may help
you avoid a collision. Before a course-correcting
brake application, Active Blind Spot Assist eval- uates the space in the direction of travel and at
the sides of the vehicle. For this, Active Blind
Spot Assist uses the forward-facing radar sen-
sors.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/ h).Important safety notes
Active Blind Spot Assist is only an aid and is not
a substitute for attentive driving. G
WARNING
Active Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.

209Driving and parking Z

Visual and acoustic collision warning
If you switch on the turn signals to change lanes
and a vehicle is detected in the side monitoring range, you receive a visual and acoustic collision
warning. You then hear a double warning tone
and red warning lamp 0043flashes. If the turn sig-
nal remains on, detected vehicles are indicated
by the flashing of red warning lamp 0043. There are
no further warning tones.
Course-correcting brake application If Active Blind Spot Assist detects a risk of a lat-
eral collision in the monitoring range, a course-
correcting brake application is carried out. This is meant to assist you in avoiding a collision. G
WARNING
A course-correcting brake application cannot always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the sides.
If a course-correcting brake application occurs, red warning lamp 0043flashes in the exterior mir-
ror and a double warning tone sounds. In addi-
tion, a display underlining the danger of a side
collision appears in the multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-cor-
recting brake application may be interrupted at
any time by countersteering slightly or acceler-
ating.
The course-correcting brake application is avail-
able in the speed range between 20 mph
(30 km/h) and 120 mph (200 km/h).
Either no braking application, or a course-cor-
recting brake application adapted to the driving situation occurs if:
R there are vehicles or obstacles, e.g. crash
barriers, located on both sides of your vehicle.
R a vehicle approaches you too closely at the
side.
R you have adopted a sporty driving style with
high cornering speeds.
R you clearly brake or accelerate.
R a driving safety system intervenes, e.g. ESP ®
or PRE-SAFE ®
Brake. R
ESP ®
is switched off.
R the offroad program is activated (vehicles
without the Offroad Engineering package).
R the Offroad or Offroad Plus drive program is
activated (vehicles with the Off-Road Engi-
neering package).
R the LOW RANGE offroad gear is activated

cases, the system may make an inappropriate
brake application, e.g. after intentionally driv-
ing over a solid lane marking. There is a risk of an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly in
the opposite direction. Always make sure that
there is sufficient distance on the side for
other traffic or obstacles. If you leave your lane, under certain circumstan-
ces the vehicle will brake briefly on one side.
This is meant to assist you in bringing the vehicle
back to the original lane.
If a lane-correcting brake application occurs,
display 0043appears in the multifunction display.
A lane-correcting brake application can be made
after driving over a solid or broken lane marking.
Before this, a warning must be given by means of
intermittent vibration in the steering wheel. In
addition, a lane with lane markings on both sides must have been detected.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detected
in the adjacent lane. The following vehicles can
have an influence on brake application: oncom- ing traffic, vehicles that are overtaking and vehi-cles that are driving parallel to your vehicle.
i A further lane-correcting brake application
can only occur after your vehicle has returned
to the original lane.
No lane-correcting brake application occurs if:
R you clearly and actively steer, brake or accel-
erate
R you cut the corner on a sharp bend
R you have switched on the turn signal R
a driving safety system intervenes, e.g. ESP ®

4MATIC (permanent four-wheel drive) 4MATIC ensures that all four wheels are perma-
nently driven. Together with ESP ®
and 4ETS, it
improves the traction of your vehicle whenever
a drive wheel spins due to insufficient grip.
If you fail to adapt your driving style, 4MATIC can
neither reduce the risk of accident nor override
the laws of physics. 4MATIC cannot take
account of road, weather and traffic conditions. 4MATIC is only an aid. You are responsible for
the distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
your lane.
! Never tow the vehicle with one axle raised.
This may damage the transfer case. Damage
of this sort is not covered by the Mercedes-
Benz Limited Warranty. All wheels must
remain either on the ground or be fully raised. Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground. !
A function or performance test should only
be carried out on a two-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage the
drive train or the brake system.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you
use winter tires (M+S tires), with snow chains
if necessary.

DSR (Downhill Speed Regulation) General notes
DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
selected on the on-board computer. The steeper
the downhill gradient, the greater the DSR brak- ing effect on the vehicle. When driving on flat
stretches of road or on an uphill gradient, the
DSR braking effect is minimal or nonexistent.
DSR controls the vehicle’s speed when it is acti-
vated and the transmission is in position 005B,005E
or 005C. You can drive at a higher or a lower speed
than that set on the on-board computer at any
time by accelerating or braking.
Important safety notes G
WARNING
If the speed driven and the set speed deviate and you activate DSR on a slippery road sur-
face, the wheels may lose traction. There is an
increased danger of skidding and accidents.
Before switching DSR on, please take into
consideration the road surface and the differ- ence between driving speed and the set
speed.
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor override the laws of physics. DSR cannot take account of
road, weather and traffic conditions. DSR is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in your lane.
You are always responsible for keeping control
of the vehicle and for assessing whether the
downhill gradient can be managed. DSR may not always be able to keep to the set speed, depend- 214
